Active Users Viewing This Thread is incorrect?!
 

So here's a weird one..

When you view the "who's online" page on our forums, it displays the proper statistics of who is online and who is viewing what thread.

But, when you go to the actual thread (showthread.php), it always says:

Currently Active Users Viewing This Thread: 1 (1 members and 0 guests)

Regardless if there's anyone else viewing the thread or not -- I've done tests with our members and it's ONLY broken on teh showthread.php.

I've reuploaded the php file incase something was wrong, and it hasn't fixed anything.

I also wanted to see if it was a style issue, but I made a brand new style with no parents, and it still doesn't show properly in the thread.

Like I said though, it shows properly everywhere else, but the showthread just won't display who's viewing the thread properly.

Does anyone have any idea what could be up?
